My ride to and from work is ~5.5 miles. After about mile three, I get numbness in my index finger and partially my middle finger.
My bike is a flat bar Specialized Sirrus w/ Grip shifts. This problem started coming up in the last month or so. When I got the bike in March, I had to grab a pair of gloves to help with the pinky and ring finger going numb.
What am I doing wrong and how do I help fix it?
